Hair loss/Androgenic Alopecia
DHT myth
Androgenic alopecia theory can be disproven since baldness increases with age despite declining androgens (including DHT).
Key Factors in Hair Loss:
- Cortisol: Promotes inflammation, upregulates TGF-B, linked to hair loss; adrenal cortex removal restores growth.
- Prolactin: Induces premature catagen phase and inhibis hair shaft growth.[1]
- Prostaglandin D2 (PGD2): Elevated in bald scalps, inhibits growth;[2] COX-2 overexpression causes alopecia, inhibitors reverse it.
- Cytokines: T1 cells (interferon-γ, interleukin-1β) from male thymus drive PGD2 synthesis, linked to hair loss.
- Aldosterone: Increases PGD2 synthase, rises with sodium deficiency;[3] spironolactone treats female baldness.
- Vitamin D: Deficiency causes alopecia via reduced keratin-31 gene expression.
- Thyroid[4]/Progesterone: Supplementation reverses alopecia.
- Scalp tension[5]
- Parathyroid hormone: Ends hair growth cycle by activating mast cell degranulation, releasing prostaglandin D2 linked to hair loss, possibly causing progressive hair loss and morning shedding like bone calcium loss.[6]
Androgen Role
- DHT-lowering drugs (finasteride) promote growth at the cost of chemical castration, topical DHT/testosterone stimulates hair in some cases.
Immune Factors
- Immunogenic proteins (gluten, casein) and endotoxin boost cortisol/cytokines, worsening hair loss.
Mitigation
- Reduce PGD2 with vitamin E, aspirin, low linoleic acid.
- Lower cortisol with sodium/blood sugar balance, avoid allergens.
- Use youth hormones (progesterone, pregnenolone, DHEA), calcium/vitamin K for blood flow.
- Zinc deficiency in men may affect thymus, aiding hair loss.
- Taurine prevented follicle fibrosis, promoted hair survival, and blocked TGF-β1-induced follicle death in human hair follicle studies.[7]
- Avoiding gluten in your diet (especially if experiencing alopecia areata and/or celiac) [8]
- Red light therapy or at least enough sunlight - simulates epidermal stem cells in the hair follicle bulge and shifting the follicles into anagen phase.[9]
- Avoid sleep deprivation tanks T3, spikes serotonin/cortisol → catabolism (hits brain/kidneys/muscles first, then hair). <7 hours/night = premature balding risk.
- A glass of milk at bedtime, with factors lowering parathyroid and stress hormones, may protect hair and improve metabolic health.[6]
- Topical T3[10]

Danny Roddy Hair like a fox[15]
Doctors often overlook the systemic nature of pattern baldness, focusing narrowly on “male” hormones and prescribing drugs like Finasteride (Propecia), which can cause serious side effects such as permanent erectile dysfunction, depression, and gynecomastia.
Androgen Hypothesis Limitations
Dr. Hamilton’s 1942 study showed that castrated men (eunuchs) do not experience baldness, linking testosterone to hair loss.
Dr. Imperato-McGinley’s 1974 discovery of the Guevedoces (males deficient in 5-alpha reductase enzyme converting testosterone to DHT) also showed immunity to baldness.
However, the androgen theory fails to explain baldness in women, newborns, postpartum mothers, and the elderly, indicating other factors are involved.
The idea of genetic sensitivity to androgens is questioned due to the high prevalence of baldness.
Bioenergetic Paradigm
Roddy proposes that baldness results from inefficient cellular energy metabolism, characterized by mitochondrial dysfunction, oxidative stress, hypoxia, and calcification in scalp tissue.
Hair follicles, as energy-intensive mini-organs, are especially vulnerable to shifts in metabolism.
The thyroid hormone (T3) plays a central role in regulating mitochondrial respiration, oxygen consumption, and carbon dioxide production, which are critical for hair follicle vitality.
Declining thyroid function with age leads to reduced energy and structural integrity in hair follicles, contributing to hair loss.
Role of Hormones Beyond Androgens
Estrogen is redefined as a “shock hormone” and agent of stress and aging rather than simply a “female hormone.”
Estrogen inhibits efficient mitochondrial respiration and promotes pro-inflammatory states, contributing to hair loss.
Progesterone opposes estrogen, supporting respiration and hair growth.
Hormones such as prolactin, cortisol, serotonin, and parathyroid hormone also play crucial roles in hair loss, largely through their effects on energy metabolism and inflammation.
Serotonin as a Contributor to Baldness
Contrary to its popular image as a “happy chemical,” serotonin inhibits mitochondrial respiration, increases inflammation, and elevates stress hormones.
It synergizes with estrogen and prolactin, exacerbating hair loss.
Serotonin regulation is therefore important in managing baldness.
Dietary Fats and Hair Loss
Polyunsaturated fatty acids (PUFAs), including omega-3 and omega-6 fatty acids, long touted as “essential” and healthy, are implicated in mitochondrial damage and inflammation.
PUFAs increase prostaglandin production, which is associated with hair loss.
Saturated fats, in contrast, support mitochondrial function and are less prone to oxidative damage.
Roddy advocates for a diet deficient in EFAs (essential fatty acids), emphasizing saturated fats like coconut oil, butter, and animal fats, while avoiding vegetable and seed oils.
Carbohydrates and Insulin Resistance
Early pattern baldness is linked to insulin resistance, often exacerbated by elevated free fatty acids.
Fructose (from natural sources like fruit) supports mitochondrial respiration and carbon dioxide production better than starches.
Starches and grains are inflammatory, promote endotoxin absorption, and worsen hair loss.
The book recommends fruit as the ideal carbohydrate source for hair health.
Supplement and Lifestyle Recommendations
Adequate protein intake (approx. 1.5 g/kg body weight) from sources low in iron and PUFAs, such as gelatinous meats, dairy, shellfish, liver, and eggs.
Adequate carbohydrate intake, favoring fructose-rich fruits over starches.
Limiting or avoiding essential fatty acids (EFAs) and highly unsaturated fats.
Use of supplements such as salt (to suppress aldosterone and stress hormones), coffee (supports respiratory energy), and vitamin D (regulates hair follicle cycling and suppresses prolactin).
Monitoring self-diagnostics such as body temperature and pulse rate to assess metabolic rate and energy efficiency.
Exposure to sunlight and red light therapy to regulate hair growth cycles and reduce prolactin.

Recommendations for a Pro-Hair Lifestyle
Self-Diagnostics
Regularly monitor body temperature (~98.6°F) and pulse (~85 BPM) as proxies for metabolic health.
Diet
Protein: 1.5 g/kg body weight daily from gelatinous meats, dairy, shellfish, liver, and eggs.
Carbohydrates: Emphasize fruits (rich in fructose and glucose) over starches and grains.
Fats: Minimize polyunsaturated fats and EFAs; prioritize saturated fats like coconut oil, butter, and animal fats.
Supplements
Salt (to taste), vitamin D (target serum 25-hydroxyvitamin D > 40 ng/dL), coffee (for metabolic support).
Environmental.
Maximize sunlight exposure and consider red-light therapy for hair follicle stimulation
Avoid
Pharmaceutical drugs like Finasteride if possible, phytoestrogens, SSRIs, and supplements that increase serotonin and estrogen.
Conclusions
Pattern baldness is primarily a systemic bioenergetic disorder resulting from inefficient cellular energy metabolism influenced by hormones, stress, aging, and diet.
The traditional androgen-centric model is incomplete and over-simplistic, failing to explain all cases of hair loss.
The health of mitochondria and thyroid function is critical to maintaining hair follicle vitality.
Hormones traditionally labeled as “female” or “male” (estrogen, testosterone) play complex, context-dependent roles in energy metabolism and hair health.
Lifestyle and nutritional interventions focused on optimizing metabolic energy, reducing stress hormones, and minimizing harmful dietary fats offer a promising path for reversing baldness.
Self-experimentation and informed skepticism are essential, as no one else will solve your hair loss problem for you.
